T0 at whom it may cancer-n.-

Be it known that we, EDWARD PRITC'HARD MARTIN, ironmaster, residing at Dowlais Iron Works, Dowlais, in the county of Glam organ, and RICHARD PRICE-WILLIAMS,- civil engineer, residing at 32 Victoria street, Westminster, London, in the county of Middlesex, England, subjects of the Queen of Great Britain, have invented a certain new and useful Tongue-Rail for Railway-Switches, of which the following is a specification. g

In our United States Patent No. 591,412, granted October 12, 1897, we have shown a tongue-rail for railway-switches of substantially the same sectional area throughout the greater part of its length, the metal being displaced from the head and from the foot, such metal as is displaced from the head being forced to the inner side of the Web, while the metal displaced from the foot is forced to the outside of the foot.

. According to our present invention the relative positions of the inner face of the head, the outer face of the Web, and the outer side of the foot remain unaltered throughout the entire length of the rail, metal being only displaced from the outer side of the head and the inner side of the foot to the inner side of the web, such metal as is displaced from the foot being forced to the inner side of the web instead of being forced to the outer side of the foot, as in our former patent. The displacement from the foot extends throughout the Whole length of the rail, but the displacement from the head throughout a portion only of the rail.

In the accompanying drawings, Figure 1 is a plan, and Figs. 2 to 13 are sections on the lines 2 2 to 13 13 of Fig.1.

a is the stock or fixed rail, and b the ton gu erail. It will be seen that in all the cross-sections, Figs. 2 to 13, the positions of the inner face a of the head of thetongue-rail, the outer face cl of its Web, and the outer side e of its foot are the same, (in Fig. 13 the face a has 5 from the foot is forced to the inner side of the web and not to the outer side of the foot,- as in our former patent.

By our improvements we adapt our former invention to flat-footed T-rails and also re= duce the deformation of the rail and the dis= placement of the metal to a minimum.

We claim as our invention--:*

1. A flat-footed tongue-rail for railwayswitches of substantially the same sectional area throughout the greater part of its length, the relative positions of the inner face of the head, the outer face of the web, and the outer side of the foot being the same throughout the entire length of the rail, such metal as is displaced from the foot being displaced from the inner side thereof, only, and forced to the inner side of the web.

2. A flat-footed tongue-rail for railwayswitches, of substantially the same sectional area throughout the greater part of its length, the relative positions of the inner face of the head, the outer face of the Web, and the outer side of the foot being the same throughout the entire length of the rail, metal being displaced from the outer side of the head through part only of the length of the rail and from theinner side of the foot throughout the whole length to the inner side of the web.
